The top 10 neighbors for Captain Mark Kelly form a tightly compressed cluster — scores run from 0.958 down to 0.943, a spread of just 0.015 — with no single dominant neighbor and no structural outlier. The composition of that cluster is the finding.

Journalists make up the largest share of the top 10: Jim Acosta (0.954), Asha Rangappa (0.952), Jim Sciutto (0.943 — just outside the top 10 but visible in the wider data), and Charles P. Pierce (0.945) all appear. Politicians follow closely: Jen Psaki (0.951) and Rep. Katie Porter (0.944). The remaining positions go to a political organization — The Lincoln Project (0.956) — an activist, Shannon Watts (0.955), a professional, Marc E. Elias (0.950), and one fellow Government Official, James Comey (0.958), who sits at the top of the list. That makes Comey the only other Government Official in the top 10; the rest of the set is journalists, politicians, activists, and political-adjacent organizations.

The cross-kind pattern here is notable: Kelly's own subcategory — Government Officials — accounts for just one of the ten neighbors. The audience shape is defined primarily by journalists and politicians, with activist and political-organization audiences rounding out the mix.

This flat, densely packed cluster suggests an audience that moves fluidly across political media and civic figures rather than anchoring to any single type.
